Screen Shots
I am so excited to have learned how to do these!
On my iMac:
Hold down together:
Command + Shift + 4 - and then select the area with the "select/drag" symbol -
Soon as I release the keys - I hear a click and the screen shot is on the desktop screen.
To open the screen shot - double click on it.\
This works great for "grabbing" just a picture of a quilt, or unwanted ads, or just one or two quotes.
